(Beginning with '90 when all 1.8L SPFIs were AWD, power and torque are shown as
90 hp @ 5200 and 101 ftlb torque @ 2800 - same as pre '90 4WDs).

Reason I'm asking is that I just installed an engine + disty + complete TBInjection
from a 2WD '87 4 dr 5 spd in my '87 4WD 3 door d/r 5 spd and it seems to be somewhat stronger over 3000 rpm than it ever did with the original engine + disty + TBI - kind of confirming that the peak torque is being developed at higher rpms.

(I know, I know. Someone is probably going to tell me that the only diff is the ECU - which
is still the orig. 4WD unit - and thus my stronger performance is all imaginary!!)

A lot fo 3rd party books and manuals have info screwed up. I would only go by owner's manuals and factory (from SUBARU only) information for this stuff.

To my knowledge...SPFI across all years, regardless of 5spd/auto/2wd/4wd or any combination of those are all the same HP/TQ per RPM...and its somewhere between 85HP and 92HP...no idea on TQ...but that 101 fig sounds about right.

I know MPFI is 97hp and something like 105~110 tq...Turbo is 111hp@5200 for 85~86, 115hp@5500 for 87+ and both have 136 tq at 2800 rpm.
